Three experiments with observers aged 6 to 21 years of age examined the integration of shape information over successive glances. Results indicated age-related improvements in the sequential integration of shape information, both when integration occurs through successive glimpses over space and when information is separated only in time. (HOD)

Three experiments explored 5- and 7-month-olds' intermodal coordination of proprioceptive information produced by leg movements and visual movement information specifying these same motions. Results suggested that coordination of visual and proprioceptive inputs is constrained by infants' information processing of the displays and have…

Investigates developmental changes in the accuracy of aimed movements made to an illuminated target lamp by children between the ages of 1.5 and 8 years. Shows accuracy decreased with decreasing availability of visual information and improved with age under all conditions. (HOD)

THE THEORY OF VISIBLE DISPLAYS IMPLIES A CONNECTION BETWEEN THE DEVELOPMENT OF PERCEPTION IN THE CHILD AND THE DEVELOPMENT OF HIS CAPACITY TO MAKE THINGS THAT STIMULATE PERCEPTION. TO VERIFY THIS, TWO STUDIES ON THE FUNDAMENTAL GRAPHIC ACT AMONG YOUNG CHILDREN CONSIDERED MOTIVATING FACTORS LIKE THE PLEASURE OF MOVING, KINESTHESIS, ACTIVITY DRIVE,…
